Description

Technical Field

[0001] The utility model relates to the technical field of ore conveying equipment, in particular to a sintered ore conveying mechanism with a protective structure. Background Art

[0002] Sintering refers to the transformation of powdered materials into dense bodies. It is a traditional process. Sintered ore is a process in which various powdered iron-containing raw materials are mixed with appropriate amounts of fuel and flux, and appropriate amounts of water. After mixing and pelletizing, the materials undergo a series of physical and chemical changes on the sintering equipment to bond the ore powder particles into blocks. After sintering, the ore is in a high-temperature state, so it needs to be transported to a ring cooler for cooling. However, since the ring cooler sometimes leaks air, the cooled sintered ore is still higher than the specified temperature. These ore is discharged from the ring cooler and falls onto the belt conveyor for transportation. The ore that has not been cooled to the standard is in contact with the belt for a long time, which can easily cause burns on the belt surface, which can easily cause damage to the belt. Replacing the belt not only increases production costs, but also affects normal feeding work, which brings great inconvenience to production operations. Utility Model Content

[0017] In the following description, many specific details are set forth in order to provide a thorough understanding of the utility model, but the utility model can also be implemented in other ways different from the description, therefore, the protection scope of the utility model is not limited by the specific embodiments disclosed below.

[0018] As Figure 1-2As shown, the sinter conveying mechanism with the protection structure comprises a rack 1, drive rollers 2 arranged at both ends of the rack 1, a conveying belt 3 arranged between the two drive rollers 2, and a plurality of support fixed rollers 4 arranged at positions corresponding to the two drive rollers 2 in the rack 1; the upper end surface of the support fixed roller 4 is supported below the upper part of the conveying belt 3; and a discharging channel 5 is arranged above the conveying belt 3.

[0019] The upper part of the support fixed roller 4 is provided with a cavity 4a; the two ends of the support fixed roller 4 are respectively provided with a water inlet joint 6 and a water outlet joint 7; the two joints are respectively communicated with the cavity 4a; the water inlet joint 5 and the water outlet joint 7 are respectively communicated with a cooling water tank through pipelines.

[0020] A spraying system is arranged on the rack 1 at a position corresponding to the front side of the discharging channel 4, and the spraying system is located above the conveying belt 3.

[0021] A water supply pump is arranged on the pipeline connected with the water inlet joint 6, and a backwater pump is arranged on the pipeline connected with the water outlet joint 7; the water supply pump is used for pumping the cooling water in the cooling water tank into the cavity 4a in the support fixed roller 4; the backwater pump is used for circulating the cooling water in the cavity 4a to the cooling water tank for cooling; after the cooling water enters the support fixed roller 4, the support fixed roller 4 is cooled; since the conveying belt 3 is in contact with the support fixed roller 4 at all times, the conveying belt 3 is also cooled; thus, when the sinter material is conveyed on the conveying belt 3, the heat of the sinter material is exchanged with the cooled conveying belt 3, so as to prevent the conveying belt 3 from being scalded due to overheating.

[0022] The spraying system comprises a spraying main pipe 8 horizontally arranged above the conveying belt 3; a water supply joint 9 is arranged on the spraying main pipe 8; the water supply joint 9 is communicated with the cooling water tank through a water pipe; a plurality of water outlet holes are arranged on one side of the spraying main pipe 8 facing the upper end surface of the conveying belt 3; a water pump is connected to the water pipe; and the water pump is used for pumping the cooling water in the cooling water tank into the interior of the spraying main pipe 8.

[0023] A water outlet nozzle 10 is arranged at the water outlet hole; and the water outlet nozzle 10 uniformly sprays the cooling water to the surface of the conveying belt 3.

[0024] A mounting vertical plate 11 is arranged on each side of the rack 1; and the spraying main pipe 8 is mounted between the two mounting vertical plates 11.

[0025] A driving motor (not shown in the figure) is arranged on the rack 1 at a position corresponding to one side of the drive roller 2; and the rotating shaft of the driving motor is connected with the roller shaft of the drive roller 2.

[0026] A plurality of support legs 12 are arranged on each side of the rack 1.

[0027] The working principle of the present invention is as follows: after the sintered ore is cooled by the ring cooler, it will be discharged through the discharge channel 5. The cooled ore falls along the discharge channel onto the conveyor belt 3 of the conveying mechanism. Before this, the driving motor controls the conveyor belt 3 to rotate, and the water pump sends cooling water into the spray pipe 8. Then the cooling water in the spray pipe 8 is sprayed out through each water outlet nozzle 10. The cooling water is directly sprayed onto the surface of the conveyor belt 3, and then the ore falls onto the wetted conveyor belt 3, which can effectively prevent the ore with residual heat from directly contacting the conveyor belt 3, thereby playing a role in cooling protection. At the same time, the water supply pump and the return water pump work successively, thereby pumping the cooling water in the cooling water tank into the cavity 4a in the supporting fixed roller 4. The cooling water circulates in the cavity 4a, which can ensure that the supporting fixed roller 4 can maintain a low temperature state, and the supporting fixed roller 4 contacts the conveyor belt 3, which can also cool the conveyor belt 3, thereby protecting the conveyor belt 3 from being scalded, thereby greatly extending the service life of the conveyor belt 3.
